Heating stove external air filtering device easy to replace and with monitoring and early warning functions

Abstract

A heating stove external air filtering device easy to replace and with monitoring and early warning functions is characterized in that an air filtering device main body is connected with a smoke exhaust pipe, and an air filtering box is mounted in the air filtering device main body; the air filtering device is characterized in that the air filtering device body is provided with a heating stove air inlet used for being connected with a heating stove air outer pipe, a heating stove smoke outlet used for being connected with a heating stove smoke inner pipe, a smoke exhaust pipe air outer pipe used for being connected with a smoke exhaust pipe and a smoke exhaust pipe smoke inner pipe used for being connected with the smoke exhaust pipe. Air for combustion of the gas heating water heater can be filtered, and cleanliness of the air for combustion is guaranteed. Meanwhile, the state of the filter can be monitored to remind the replacement of the filter cotton of the filter, the filter cotton is easy to disassemble, clean, replace and install, and the machine does not need to be disassembled in the process, so that the use safety of the machine can be ensured, and the after-sales service cost of a user is saved.

Description

technical field [0001] The invention belongs to the field of combustion air filtration for gas heating water heaters, in particular to an external easy-to-replace air filtration device for a wall-hung boiler with a monitoring and early warning function. Background technique [0002] When the heating furnace is burning, pollutants in the air (such as PM2.5, PM10, SO2, NOx, dust, particulate matter, etc.) enter the heating furnace through the supply and exhaust pipes for combustion, under the action of the combustion chemical reaction, they are easily deposited in the heat exchanger. The formation of hard deposits on the water surface will cause local overheating, resulting in the formation of scale on the water side, causing a vicious cycle of local overheating, and eventually the heat exchanger will be pitted and burned. After long-term operation, a large amount of dust and particles will accumulate at the inlet of the fan and burner mixture of the heating furnace, which wil...
